本文介绍了一个员工管理控制器的具体实现，包括展示所有员工列表、获取指定员工详细信息以及更新员工信息的功能。通过Spring MVC注解实现了请求映射和依赖注入。

@Controller
@RequestMapping(value = "/employee")
public class EmployeeController {

    @Autowired
    private IEmployeeService employeeService;

    @Autowired
    private IDeptService deptService;

    @RequestMapping
    public ModelAndView index() {
        ModelAndView view = new ModelAndView("employee/list");
        List<Employee> employees = employeeService.list();
        view.addObject("list", employees);
        return view;
    }

    @RequestMapping(method = RequestMethod.GET, value = "/detail/{employeeId}")
    public ModelAndView detail(@PathVariable Integer employeeId, ModelAndView view) {
        view.setViewName("employee/form");
        view.addObject("employee", employeeService.getById(employeeId));
        view.addObject("depts", deptService.listAll());
        return view;
    }

    @RequestMapping(method = RequestMethod.POST, value = "/update")
    public String add(Employee employee) {
        if(employee.getDept().getId() == null) {
            employee.setDept(null);
        }
        employeeService.saveOrUpdate(employee);
        return "redirect:/employee/";
    }

}
